Yes. Enter your UK registration in the search tool to see tyres matched to your vehicle’s recorded fitment, then double-check the size and ratings against the door placard or owner’s manual.
Look at the tyre sidewall (for example 255/65 R16), the driver’s door jamb placard, or the handbook. If you have aftermarket wheels, confirm the currently fitted size and required load rating before ordering.
Choose a tyre with a load index that meets or exceeds the vehicle manufacturer recommendation. This matters for a 110 Defender because of higher vehicle weight, passengers, payload and towing, so do not downrate even if the size looks correct.
After selecting your tyres, pick a nearby fitting garage and an appointment time during checkout. Your tyres are delivered to the garage, and you attend the booking for fitting, balancing and safe disposal of the old tyres where included.
Road legality depends on the tyre being E-marked (or UKCA where applicable) and meeting UK tread depth rules, plus having suitable speed and load ratings. Aggressive off-road patterns can be road legal, but may be noisier and handle differently on wet roads.
